I'm trying to tidy up the widget creating/layout code in a rather large QDialog which contains many QGroupBox widgets each of which contains a list of buttons. For each groupbox the buttons will all be QPushButton or all QCheckBox.

1. I've managed to code a working method which successfully creates the groupbox/buttonlist pairs but I need a bit of help. The code currently is something like this:
   

   def create_groupbox(self, lvalues, widget='QPushButton'):
       ... ...
       buttonlist = []
       for val in lvalues:
           ... ...
           if widget == 'QPushButton':
               button = QPushButton()
           elif widget == 'QCheckBox':
              button = QCheckBox()
           button.setText(val)
           ... ...
           buttonlist.append(button)
       ... ...
       return buttonlist, groupbox

   Is there better 1-line code for the red bit?
2. A follow-up question. If I've previously created a groupbox/buttonlist pair using the above method,
   e.g. self.blist, gbox = self.create_groupbox(['1em', '2em', '3em'])
   and elsewhere in the code I need to know whether self.blist was created using QPushButton or QCheckBox, is there a test I could use on self.blist[0] to answer that question?
